Interested parties are representatives or individuals who AEMO determines have an interest in regulated network planning and development – such as large industrial-load electricity transmission customers – who may offer a non-network solution to reduce electricity use during times of peak demand.

This type of solution may defer or remove the need for regulated transmission investment, while still ensuring adequate network capability to achieve reliability of supply.

Interested parties also include an end-user or a representative who, in the opinion of the Australian Energy Regulator (AER), has or identifies themselves to the AER as having the potential to suffer a material and adverse market impact from the proposed electricity transmission investment that is the preferred option identified in the Project Assessment Conclusions Report.
